Figure 2From: FlexSnap: Flexible Non-sequential Protein Structure AlignmentFlexible Structural Alignment by AFPs chaining. When extending the alignment R = {P1, P2, P3}, the score of extending R with each AFP is computed and we extend the alignment with the AFP that gives the best score. The score S(P4, P2, P3)) indicates the score of adding P4 to the region composed of P2 and P3.Back to article page
